I decided to paint the fog light surrounds and the upper and lower grille today in black gloss to match the splitter, They we're originally a grey matte (the pictures don't make it appear much different, guess it looks better in real life)

Brought the grey primer and black gloss paint from Halfords so cost about £12 to do.

I have attached some pictures, Be good to hear what you think just deciding what to do next!
